PEARL®

The core of Ostara’s solution is the Pearl. A fully customizable and modular treatment solution, Pearl fits into your main or side-stream operations removing phosphorus from your treatment system by adding magnesium in a controlled pH setting. This allows nutrients to crystallize into highly pure fertilizer granules, which are harvested, dried and bagged – ready for distribution and sale as Crystal Green®.
